Research Subjects

I started my PhD on dynamic clustering with N. Schabanel. In the end, I changed subjects to work with Ted Selker on usability of security and its applications to e-democracy.

I'm working with L. Gabasova and S. Kachanovich on Computational Geometry, Metaheuristics, and their application to planetary science.

I joined the Random Sample Voting Project in January 2016 to study how to prevent vote selling and am responsible for the creation and continued development of the RSV Simulator. I'm also in the process of publishing a book on the use of randomness in politics.

Papers and Conferences

Security and Usability

Paper and slides on improved passphrase choice from ACSAC 2018. French paper and slides at Algotel 2018.Preprint on a mental password management algorithm. French paper and slides at Algotel 2018.Preprint on improved single-use codes for manual transcription.

Voting Theory and e-democracy

Slides from the first plenary talk at the Global Forum on Modern Direct Democracy 2016. Paper (French) on sample voting from Algotel 2016. Transcript of an interview (and blurry video) with Audrey Tang, digital minister of Taiwan. Paper and slides on trust and RSV at TeSS 2017 (2nd best phd award). Complete paper in IJDSST. Paper on the difficulties of implementing voting technology at STAST 2018.

A paper on polytope nesting with Leila Gabasova and Siargey Kachanovich should be here soon.Note on a computational topology problem (inflating balls in a metric space).

Graph Theory

Paper on roots of graph polynomials with Janos Makowsky and Elena Ravve (Editors' Choice, European Journal of Combinatorics). I previously worked with Oded Lachish and Eldar Fischer on long paths and cycles in 2- and 3-connected graphs. A link to the paper will be here eventually.
